KickJava.com has introduced a Java Source Codes Repository of over 20 million lines of codes, with more being added. "The unique feature is that all source codes are extensively cross-referenced and linked to JDK APIs, so that it can be used to track the call stack easily." Code is organized in sections by package, so the top level consists of "org", "com", "java", etc.
